什么是 IP 轮换，如何设置以绕过封锁？

What is IP address rotation and how to set it up to bypass blocks?

You've probably come across the term "IP rotation". But if you ask someone to explain what it is and why it's needed, not everyone can give a clear answer. Yet, for modern internet marketing and ensuring anonymity, this is a key tool. Let's figure out how this technology works and how to make it work for you.

What does IP address rotation mean?

First, let's recall the basics. An IP address is the digital passport of your device on the network. It comes in two types:

• IPv4 (older and scarce)

• IPv6 (new, more spacious)

IP address rotation is a technology where your real or proxy address is regularly changed to a new one while working with a target website. Imagine you go into a store. In the same store, sellers will quickly remember that you constantly come in and never buy anything. But if you go to different stores, you're just an ordinary passerby.

In the digital world, it works the same way. With a standard connection through a home ISP, you get a dynamic IP from a shared pool. Providers are forced to change them because there are always more users than available addresses.

However, for professional tasks, such "natural" rotation is not enough. This is where specialized proxies come to the rescue, such as IPv4 Dedicated Proxy, which give you clean, dedicated addresses for stable operation, or services with advanced automatic rotation.

What is proxy rotation and why does a business need it?

If providers change IPs to save resources, professionals do it deliberately and to achieve specific goals. Proxy rotation is the process of intentionally changing addresses, allowing you to manage hundreds and thousands of connections from a single device.

What is it for?

The main task is to bypass blocking and not get noticed. Modern websites have learned to detect suspicious activity. If you send 1000 requests per minute from one IP, the security system will instantly block you. If each request comes from a new address, the site sees 1000 different "regular visitors" and calmly lets them through.

There are different methods for organizing such a change: manual configuration or automatic algorithms. For example, when using browser extensions (Chrome), you can change the address in a couple of clicks.

Also, there are ready-made solutions with automatic rotation that take all the work upon themselves. You get a single entry point, and the system automatically selects a new, "clean" IP address for each of your requests from a huge pool.

What is a rotating proxy?

Essentially, it's just an IP address that doesn't live long. The system gives you one address to send a request, and as soon as the task is completed, it is replaced with another.

Why use proxy rotation? 8 tasks it solves

The main problem when collecting data is a ban. Sites track suspicious activity and block access. IP rotation solves this – each of your requests comes from a new address, and the site sees not a bot, but regular visitors. The higher the quality of rotation, the higher the chance of staying undetected.

In practice, proxy rotation is used wherever stable data collection without blocks is required. Main areas:

1. SEO monitoring. SEO agencies use rotation to check website positions in different regions. With a German proxy, you see the search results in Germany, and with a Brazilian one – in Brazil. Rotation prevents the search engine from "remembering" your bot and distorting the results.

2. Analytics and data collection. Automatic proxy rotation is needed by analytical companies to collect data from websites for market research and competitor monitoring.

3. Bypassing geo-blocks and price discrimination. Companies can use IP address rotation to bypass regional restrictions and avoid inflated prices. IP switching also allows you to bypass request limits and gain access to content restricted by geolocation.

4. Data validation. Advertising networks and analytical platforms check traffic "honesty". To avoid being blocked, a constant change of digital "identification" is necessary.

5. Maintaining network load. To maintain stable network operation, IT companies use IP address rotation for their bots that send requests. This helps distribute load evenly and prevent overloads.

6. Bypassing IP bans. During large-scale data collection, an IP ban is a matter of time. Rotation distributes the load, and the chance of getting blocked approaches zero.

7. Bypassing CAPTCHA. Captchas are the main enemy of automation. They trigger when the system sees suspicious activity from one address. If each of your requests looks like a new user, the likelihood of a captcha appearing decreases many times over.

8. Confidentiality. For competitive intelligence, maintaining anonymity is extremely important. IP rotation muddies the trail, preventing all requests from being tied to a single source.

IP address rotation methods

There are several methods by which providers change IP addresses.

• Pre-configured IP rotation. The address changes strictly according to a timer (e.g., every 10 minutes).

• Specific rotation. The user manually chooses which IP from the list to use to go online.

• Random rotation. The most popular method for web scraping. The system itself assigns a random IP for each new connection.

• Burst rotation. The address changes after a certain number of connections (e.g., after every 10 requests).

• Tool for proxy rotation

The most reliable way for a business is to use a ready-made solution, such as Vless VPN Premium. You don't need to think about technical details. Our system works on the "set it and forget it" principle.

1. Add the proxy rotator to your tariff plan by logging into your account or contacting us.

2. You receive one common address (connection address) that gives you access to your entire list of proxies.

3. Each time you send a request, the system issues a new IP address.

After purchasing datacenter proxies, you will receive detailed instructions to help you get started quickly.

A special proxy rotation service makes it easier to bypass blocks during web scraping. In addition, it reduces the risk of errors in IP rotation setup.

Important: residential proxies already have built-in automatic rotation, so an additional rotator is not needed for them. But for datacenter proxies, using rotation is recommended – this makes the probability of blocking even lower.

• Manual setup

Proxy rotation can also be done manually, with the user independently changing proxy settings in the browser, for example in Google Chrome, to switch between different IP addresses.

• Programmatic method

Developers can integrate rotation directly into code. For example, using the Python Requests library. We provide ready-made snippets and detailed guides for setting up rotation for Python, PHP, and other languages.

• VPN rotation

Classic VPNs can also change addresses when switching between servers. However, their rotation is usually less flexible and not tailored for web scraping tasks, unlike proxies.

• Automatic update from provider

The simplest but useless method for business is restarting the router. The home provider will give you a new dynamic IP, but this will solve the ban problem only for a short time and is not suitable for automation.

Comparison of methods: Proxy Rotator vs Manual setup

So that you can make an informed decision, let's compare the two main approaches.

Which option to choose?

Now you understand the difference between a simple IP change and professional rotation. If you are engaged in data collection, market monitoring, or any other activity where stability and anonymity are important, using "manual" methods will end up costing you more due to downtime and lost data.

Frequently Asked Questions

Is it worth using IP address rotation?

Yes, IP rotation enhances security during web scraping, as each request is sent from a new IP, mimicking the actions of different users and reducing the risk of blocking.

Why is it important to use IP address rotation?

Many websites employ anti-scraping protection to detect and block bots. IP rotation helps mimic the behavior of ordinary users, allowing you to operate on the site less noticeably and with a lower risk of blocking.

What are the most common mistakes when using proxies and IP rotation?

Problems most often arise due to incorrect rotation setup. As a result, the same proxies are used too frequently, which makes activity resemble that of a bot and can lead to a ban.

Does a rotating proxy increase the success rate of web scraping?

Yes. With proper rotation setup, you can bypass site restrictions and perform web scraping tasks more reliably.

Is IP address rotation legal?

Using IP rotation increases the level of anonymity and security because requests are sent from different IP addresses and different geolocations. Using proxies is generally legal as long as it does not violate laws. However, in some cases, it is better to consult a lawyer.

How often should crawlers change their IP address?

When using datacenter proxies, it is recommended to change the IP for each new session. Residential proxies typically have automatic rotation.

How to set up IP rotation for a web crawler?

This can be done in two ways: use a proxy provider with built-in IP rotation, or set up your own system by connecting several IP addresses and using them alternately in your crawler's request logic.

How to change an IP address every second?

To do this, you can use a proxy service with frequent IP rotation or set up a script that quickly switches between several IP addresses or VPN nodes.

Why don't rotating proxies arouse suspicion from websites?

They use different IP addresses and thereby mimic the actions of ordinary users. If you additionally vary the time between requests and the user-agent, website security systems will less often recognize such activity as bot operation.
